45W AC adapter with 4.5*3.0mm blue tip

This 45 watt power supply replaces the original charger for HP 14 inch laptops across the DK DQ DF DH DS AC AK AL BA CK AX FQ and DY series. It accepts 100 to 240 volt AC input at 50 or 60 hertz for worldwide use. The three pin outlet plug connects to standard mains sockets. Buyers needing a higher wattage unit for larger notebooks or gaming models should look elsewhere.

Worldwide 100 240 volt input and three pin plug

The adapter operates on any mains voltage from 100 to 240 volts without a separate voltage selector. The included three pin power cord fits standard wall outlets in the UK and many other regions. No extra travel converters or regional cables are bundled. Users in countries with different socket types will need a separate plug adapter.

19.5 volt 2.31 amp output for listed 14 inch models

Delivering 19.5 volts at 2.31 amps the unit matches the 45 watt requirement of the compatible HP 14 inch laptops listed in the specifications. It powers the notebook and charges the battery simultaneously while the system runs typical productivity workloads. The fixed 4.5 by 3.0 millimetre blue tip connector fits only the models named; it will not suit devices that require a different tip size or a higher current rating.

Questions about this item

How often will the 4.5*3.0mm blue-tip connector need replacing?

The connector is a fixed part of the cable; it only needs attention if the tip or cable sheath shows physical wear from repeated insertion.

What limits continuous output during all-day charging?

The adapter is rated for 45W at 19.5V 2.31A; sustained loads at that level are its design ceiling.

How much heat or noise does the unit produce when running 24/7?

With no fan and a sealed enclosure, it runs silently; warmth stays within normal limits for a 45W supply at 100-240V input.
